Appendix 1 of Postgraduate Professional Education Regulations “Forensic-Clinical Chemist GTFCh“


The applicant must acquire thorough specific knowledge, experience and skills in the area of forensic-clinical chemistry according to scientific and technical standards. Amongst others it is required
  • Forensic-clinical findings reports (if possible expert reports) under consideration of scientific standards and prevailing case law
  • Publishing independent scientific papers in acknowledged journals
  • Participating in postgraduate professional education arranged by the GTFCh
  • Participating in scientific events (workshops, conventions etc.) and, if necessary,
  • Delivering oral expert opinions, particularly in criminal proceedings, if this is possible in the context of the field of activity.
The applicant may substantiate acquired knowledge, experience and skills by additional
  • Visits in other postgraduate professional education institutions
  • Participation in postgraduate professional education arranged by other institutions related to forensic-clinical chemistry (associations, chambers)
  • Conducting of own lectures and courses
  • Successful participation in postgraduate university courses or seminars in related topics.
The applicant needs postgraduate professional and continuing education in the areas (postgraduate professional education modules) listed below:
